FREDERICK A. REDMON, OF SAN FRANCISCO, CALIFORNIA.

CARBURETER.

SPECIFICATION forming part of Letters Patent No. 583,818, dated June 1,1897.

Application filed April 1, 1896. Serial No. 585,772. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK A. REDMoN, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements inVaporizers and Carbureters and I do hereby declare that the following isa full, clear, and exact description thereof.

My invention relates to apparatus for carbureting air, and in the formin which I have embodied it is used for producing an explosive mixtureof air and vapor for operating a gas-engine.

My apparatus comprises a vaporizer for oil, means for mixing the vaporof oil with hot air, and means for regulating the supply of oil andadmitting it automatically to the vaporizer.

The object of my invention is to do away with the heavy, cumbersome, andexpensive carburetors commonly employed and to provide instead a smalland simply-constructed vaporizer and carbureter which can be attacheddirectly to the gasengine, if desired, and which will be convenient aswell as perfectly safe in use.

I have illustrated my invention in the accompanying drawings, in which--Figure 1 is a central vertical section of the apparatus. Fig. 2 is acombined plan and horizontal section of the same.

Ais a cylindrical metallic chamber, the bottom of which is preferablyrounded to form an oil-receptacle.

B is a pipe entering the chamber and which is supposed to supply airheated by a coil in the exhaust-passage of the gas-engine.

O is a pipe which enters the chamber near its bottom and which suppliesoil from any suitable tank conveniently located.

D is a plate which closes the top of the chamber and from which a pipe Econveys the carbureted air to the gas-inlet of the engine. Within thechamber is a cylinder F, depending from the top plate D and havingsecured within it screens G G, between which -is a body of some porousmaterial.

Below the lower screen and resting on the bottom of chamber A is a shellH, having a serrated lower edge or otherwise provided with openings toallow the oil to enter freely.

This shell incloses a float I, which is sup ported upon the body of oiland rises and falls as the latter changes: its level. An arm 1 projectsfrom the float through aslot 2 in the shell and is pivoted in a standard3. This arm forms a lever, the free end of which is formed into a earn4, which bears on the end of the valve-stem 5 in the oil-pipe O. Aseat 6is formed in the pipe for the valve 7 which is kept seated by a spring8, excepting when moved by the cam. If the oil in the chamber A fallsbelow a certain level, the cam will open the oil-valve and admit oiluntil the float rises enough to close the valve again. Thus the supplyis automatic and regulated. The chamber A forms a hot-air space abovethe oil. The air can circulate around the cylinder F and shell II, butis compelled to pass downward in contact with the oil. The vaporproduced by the hot air changes the air or carburets it, and theresultant explosive or ignitible mixture rises between the shell 11 andthe cylinder F and through the porous filling and escapes through thepipe E ready for service in the engine. The porous filling entirelyprevents any danger of explosion by a possible back draft of carburetedair.

The device can be attached to any convenient part of the engine andforms an exceedingly simple, cheap, and convenient carbureterparticularly well adapted to supply vapor to small gas-engines,especially in situations where it is inconvenient to use the ordinarylarge carbureters.

WVhat I claim is- 1. In combination, the outer casing, the bottomlessinner casing depending from the top thereof, the sleeve supported in thebottom of said outer'casing and extending upwardly within the innercasing, the porous filling and the screen extending entirely across theinner casing for supporting the same, the upper edge of said sleevecontacting With said screen, and the inlet and outlet pipes,substantially as described.

2. In combination, the outer casing, the outlet-pipe in the top and theair and oil inlet the valve under spring-tension for closing Intestimony whereof I have aflixed my said oil-inlet pipe, the standardarranged to signature, in preseneeof two witnesses, this one side ofsaid sleeve, the lever carrying the 14th day of March, 1896;

cam at one end pivoted to said standard, the FREDERICK A. REDMON. 5opposite end of said lever extending through Witnesses:

a slot in said sleeve, and the float carried L. W. SEELY,

thereby, substantially as described. F. E. MONTEVERDE.
